FLANGE OF WARP-BEAMS USED IN LOOMS FOR WEAVING- Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed November 29, 1904. Serial No. 234.792.

To all whom it may concern:

Be it known that I, WILLIAM BLAoKBURN, a subject of the King of Great Britain, residing at 16 Gisburn street, Broughton Road, Skipton, in the county of York, England, have invented new and useful Improvements in and Relating to the Flanges of VVarp-Beams Used in Looms for Weaving, of which the following is a specification.

My invention refers to improvements in and relating to the flanges of warp-beams used in looms for weaving; and my improvements consist of an improved construction of the flanges and of means for clamping and firmly securing the flanges in any positions to which they may be adjusted on the warp-beam.

I illustrate these improvements on the accompanying three sheets of drawings, in which Figure 1 is a side view, and Fig. 2 a front elevation, of one of my improved flanges and the improved means for securing the same on a warp-beam. Figs. 3 and L are two views showing the improved flange made in two parts.

In carrying my improvement into effect I prefer to form the flange a of wood in any suitable number of thin layers glued or otherwise secured together. In the example illustrated by Figs. 1 and 2 the flange a is shown composed of five layers, numbered 1 2 3 4 5, respectively, the layers 2- and 4 being thick compared to the remaining layers. I also prefer to have the grain of the wood running in one and the same direction in the layers 2 and 4 and in the opposite direction in the layers 1, 3, and 5. The flange a may also be strengthened,if desired ,by spinning or shrinking a metal hoop or shield upon its periphery somewhatin the well-known manner employed for strengthening wooden bobbins or pirns. In place of wood I may build up the flange in like manner of any convenient number of disks of papier-mach or wood-pulp; but I prefer the wood layers, as described.

The flange a has of course a central hole 6 to enable it to be passed onto the warp-beam 0, and to secure it firmly in any desired position thereon I employ according to my improvement any suitable and convenient number of wooden or other segments (Z, each of which is secured to the flange a by a bolt 0,

nut f, and washer g, the bolte passing through to enable this feature to be clearly seen. As shown by this figure, the hole 00 in the segment, being much larger than the bolt, is equivalent to a slot, and thus each segment (Z has a certain amount of play or movement below the nut f. The segments cl are encircled by a steel ring or other suitable metal clamp it, the ends of which are turned outward at right angles and through them is passed a bolt 7:, with nut j and washer is, so that by tightening up the nut j the ends of the steel ring 7 are caused to approach one another until the segments d are tightly compressed upon the warp-beam 0 and the flange a is firmly clamped and secured thereon at right angles to the beam.

In the construction illustrated by Figs. 3 and 4 the improved flange a is shown made in two parts to enable the flange to be readily placed on and removed from the warp-beam 0 without taking the beam out of the loom.

In order to secure an even and smooth surface where the two parts of the flange join, I place a dowel or projection or two or more projections in the edge of one part to engage corresponding recesses in the edge of the other part of the flange. In the example shown I employ one such projection a and a corresponding recess on each part. I thus make the flange firm and rigid and the joint even when the two parts are united, and I may attain this result by other means; but I consider this the simplest and most satisfactory method. In this construction with a split flange I prefer to make the clamping-ring It also in two parts with two sets of bolts 7;, nutsj, and washers It to clamp the segments 03, with the flange a in position on the warp-beam 0. With either construction and with this method of securing the flanges upon the warp-beams the flanges can be set or adjusted to any desired distance apart and can then be firmly and rigidly fastened upon the warp-beam.

I wish it to be clearly understood that I can employ my improved flange whether made in one part or several parts in conjunction either with my improved means or with any other known and suitable mode of securing it upon the warp-beam, and in like-manner I can employ my improved means for securing flanges on warp-beams in conjunction with my improved flange or with any other known and suitable construction of flange; but I prefer to employ the improvements in combination as illustrated by the drawings.

What I claim, and desire to secure by Letters Patent of the United States, is r 1. In combination with a warp-beam, a flange therefor and means for securing said flange to the beam consisting of a number of segments connected to the flange but capable of bodily movement with respect thereto and means for clamping said segments against the beam, substantially as described.

2. In combination with a warp beam, a flange therefor and means for clamping said flange to the beam consisting of a number of segments bolted to the flange each segment being capable of bodily movement with respect to its bolt and a clamping-ring for clamping said segments against the beam, substantially as described.

3. In combination with a warp-beam, a
